A Step-by-Step Guide to Filing Error‑Free ITR
Follow this detailed roadmap to avoid common pitfalls—and leverage new tax updates.
1. Choosing the Right ITR Form
| Form | Who Should Use It |
|---|---|
| ITR-1 | Salaried/Pensioners with income up to ₹50 lakh |
| ITR-2 | Individuals/HUFs with capital gains, foreign income, etc. |
| ITR-3 | Individuals/Partnerships with business or professional income |
| ITR-4 | Presumptive business income (Sugam) |
| ITR-5/6/7 | Firms, Companies, Trusts, Political parties, etc. |
Tip: The portal auto-validates form selection. If rejected, correct and re-file immediately to avoid delays.
Example: Rajesh, a photographer, used ITR‑1 despite capital gains; he refiled ITR‑2 and paid ₹1,000 late fee.
2. Comparing Old vs New Tax Regime
| Feature | Old Regime | New Regime |
| Tax Slabs | 5%–30% | 5%–25% |
| Deductions Allowed | Yes (80C, 80D, HRA, etc.) | Limited |
| Standard Deduction | ₹50,000 | Nil |
| Ideal For | High-deduction claimers | Simpler, lower rates |
3. Reconcile Form 26AS & AIS Thoroughly
- Download Form 26AS from net banking or e‑filing portal.
- Cross-verify TDS entries: salary, interest, dividends, rent.
- Match AIS for specified financial transactions (e.g., credit card spends > ₹1 L).
Discrepancies trigger notices and refund delays—so don’t skip this!
4. Report All Taxable Income Sources
Include every income stream to avoid under-reporting penalties:
- Bank Interest: Savings, FDs, NRO accounts.
- Capital Gains: Equity, debt, property, crypto.
- Rent: Self-occupied vs let-out—pay attention to municipal taxes.
- Freelance/Gig Earnings: Include platform payments (e.g., Upwork).
- TDS on E-commerce: New 1% TDS rule for online sellers applies.
Pro Tip: Use a Digital Income Tracker like Google Sheets for real-time updates.
5. Claim Only Valid Deductions
Proof-backed deductions save taxes—wrong claims invite hefty fines:
- Section 80C: PPF, ELSS, NSC, life insurance (limit ₹1.5 lakh).
- Section 80D: Health insurance premiums (self, family, parents).
- HRA: Rent receipts, rent agreement, landlord PAN.
- Home Loan Interest: Up to ₹2 lakh under Section 24(b).
Caution: Fabricated proofs can attract penalties up to 200% of the tax saved under Section 270A.
6. E‑Verification Done Right
Complete e‑verification within 30 days via:
- Aadhaar OTP (ensure mobile is linked and active).
- Net Banking (one-click e‑verify).
- DSC (for companies and partnerships).
- ITR‑V by Post (signed copy to CPC Bangalore).
Missed e‑verification = invalid return!
